嵌入在HTML中的JAVA Applet在操作过程中挂起

Question

我有一台Web服务在一台机器上运行，我想通过Applet访问该Web服务。独立的Applet完美无瑕地运行。但是，当我将该applet嵌入到html文件中时，真正的问题就开始了。由于某些客户端限制，我需要将小程序嵌入到Html文件中。当我打开html页面但不访问Web服务时，applet开始。

我知道Applet必须签名才能访问所有可用的资源。我已经签署了罐子，但它仍然挂起。为了解决这个问题，我想到了监视从Web服务运行的客户端到服务器的网络流量。我发现有一些区别..当我运行独立的JAVA Applet（JAR文件）时：它调用精确的Web服务链接并获取响应。另一个最重要的要注意的是，它调用javaw.exe和完美的POST请求（下面显示的第三个请求）。

当我运行嵌入在HTML文件中的同一个applet：我得到不同的结果，其中，它调用的java.exe，并呼吁不当链接到网络服务获取（指着serviceexception.class而不是POST/LEDLabServer /服务/闪烁）

PS：我正在使用JAXRPC进行Web服务。

有人可以帮助我吗？

Answer 1

的问题是从你的日志很明显：

HTTP：响应，HTTP/1.1，状态：未发现，网址：/LEDLabServer/sampleBlinkProxy/javax/xml/rpc/ServiceException.class

您没有将类文件安装在正确的位置，所以浏览器找不到它们。
